Who Has Technics Headshell with Azimuth Adjustment?

All my headshells have ''azimuth'' + effective length correction.
The 4 pin connector in the headshall can not only be rotated in
order to get the stylus straight but also to get the stylus eff.
length correct by moving the connector back and fort.
By Technics are fastening threads , alas, at the under site so the
only way to adjust the eff. lenght is to move the connector back
and fort.  

I own SP-10,mk2 but use FR-64 S with this TT. I bought many
headshells all with ''azimuth'' adjustment . The Technics headshells
are suitable for (MM) carts which don't have screw threads. Those
can be fastened from underside so much more easy then with
nuts and screws.

The worthless method should not be substituted for the same
valuation or opinion. There are those small round levels which
can be put on the headshell . So it seems obvious that without
azimuth provision in the headshell those levels will be of no help.
BTW not only azimuth but also SRA , arm level and eff. length 
can be adjusted this way; by ''movable connector''.  If the cart is correctly made then all parameter can be adjusted in this way.  

Whoever try to fasten carts without screw threads with screws and
nuts know how irritating this way of fastening is. For such carts the
AT headshells are much more easy to use.  Because screw threads
are at the under side no nuts are needed . Holding those small nuts
fast while trying to get the screw in is an nightmare. But because
there are only 3 such threads the effective length can be only adjusted  with movable 4 pin connector . To put this otherwise AT
headshells are not ''universal''. They are suitable for the carts without
screw threads.
